I was preparing the upload of an alternative scan of https://e-hentai.org/g/616536/1fefb502ac/, when I noticed that the old translation of it didn't seem to be available in the site. So, I decided to upload it.
I have no connection with this translation.

be nice if we could get tropism 2 translated as well

The Ryuunsuke ending was hilarious. They said it would have been even better if he had fucked more girls both from his own Manga as well as cameos from Ranma. Ataru fucking female Ranma would have been great.

Odd though that the doujin only showed him fucking two of the girls in the "stupid trio".
